NatWest dropped to fifth after being last years' highest ranking bank, with Santander at second, Lloyds bank third, HSBC fourth, Nationwide sixth and the Co-operative seventh.

Forrester analyst, Stephen Walker said: "It is no secret that UK banks were slow to take mobile banking seriously.

"Some of last year's laggards have overtaken last year's leaders, and many UK banks now offer mobile sales functionality - ahead even of their peers internationally. All UK banks now do well where it matters most to customers - across money movement, balance checking and transaction history search."

Walker added: "Barclays has spent time and money on mobile - and it shows."
